  1. investigating Jun 16, 2026, 03:13 PM UTC

    We are investigating reports of intermittent clicking sounds affecting a subset of voice calls. At this time, the issue does not appear to impact all traffic, and we have not identified a common source or pattern among the affected calls. Our Operations team is actively engaged with our upstream carrier partner, Tandem, to isolate and determine the root cause. We continue to escalate internally and are closely monitoring the situation while additional troubleshooting is performed. We will provide further updates as more information becomes available.

  2. identified Jun 16, 2026, 07:01 PM UTC

    The NUSO Operations team, in coordination with our Tandem and originating carrier partners, has identified potential network elements that may be contributing to the intermittent clicking sounds reported on a subset of inbound calls. As a precautionary measure, we have started implemented routing adjustments designed to reduce the likelihood of calls traversing the suspected paths while our investigation continues. At this time, the issue remains intermittent and does not affect all inbound traffic. Our teams continue to actively monitor call quality and work with our partners to further validate the source of the issue and implement any additional corrective actions as needed.

  3. resolved Jun 16, 2026, 07:38 PM UTC

    All currently identified affected calling areas and associated telephone numbers have been routed around the suspected network path. While this mitigation has reduced the impact for known affected traffic, our investigation remains ongoing. If you continue to experience call quality issues, please contact our NOC with the affected telephone numbers and call details. Our team can review the reports and, where applicable, include additional numbers in the current mitigation efforts while we continue working with our carrier partners toward a permanent resolution.

    We are currently experiencing an issue with the X3 instance on our Green platform and are actively working to resolve it. All other instances remain fully operational. Resellers who manage their own DNS records may need to update them to route traffic to available instances during this outage.

  2. identified Jul 16, 2025, 04:39 PM UTC

    We have identified an issue impacting the X3 instance on our Green platform. Our internal systems remain unaffected due to built-in redundancy, and no disruption is being observed across other instances. Resellers who manage their own DNS and have not yet updated their records away from the X3 instance may experience service interruptions. All other services continue to operate normally.

  3. identified Jul 17, 2025, 07:32 PM UTC

    Due to the nature of the issue with the X3 instance, it needs to be rebuilt in coordination with the manufacturer. This work will be performed over the weekend with the goal of restoring service Monday morning. All other instances continue to operate normally. We will provide updates once the rebuild is completed. Thank you for your patience during this extended maintenance period.

  4. monitoring Jul 21, 2025, 03:01 PM UTC

    The rebuild is now fully complete, and all systems are ready. However, final data replication is taking a bit longer than expected. To ensure a smooth transition and avoid any potential disruption, we’re holding off on shifting live traffic until overnight tonight. We expect everything to be fully live by early tomorrow morning.

    All rebuild work remains complete, and systems are fully prepared for cutover. However, final data synchronization is still in progress and requires additional time to ensure consistency across environments. To avoid any service impact, we are extending the transition window. The go-live is now targeted for the end of this week. We’ll continue to monitor progress closely and will provide another update ahead of the final cutover.

  7. resolved Jul 25, 2025, 01:13 PM UTC

    All rebuild activities are fully complete, and the systems have been online and handling traffic without issues since last night. No further work is required, and all services remain fully operational. This incident is now resolved.

  2. investigating Jun 12, 2025, 07:19 PM UTC

    We are continuing to investigate this issue.

  3. monitoring Jun 12, 2025, 07:39 PM UTC

    We’ve implemented adjustments to improve inbound call handling on the Orange Platform. Since these changes, we’ve observed a significant reduction in call failures, and service is currently performing near expected levels. Our investigation identified a hardware issue on one of the servers involved in certain call handling scenarios. Traffic has been redirected to redundant systems, which are currently managing call volumes effectively. While we do not expect widespread impact, intermittent call issues may still occur in rare cases until repairs are completed. Our team is actively working on restoring full system redundancy and will continue to monitor the platform closely.

  4. monitoring Jun 12, 2025, 09:54 PM UTC

    Following our earlier adjustments and traffic redirection to redundant systems, we’ve continued to monitor inbound call handling on the Orange Platform. While the situation has improved, we are still observing some intermittent instability in certain scenarios. We’ve identified a specific hardware component contributing to the issue. Replacement hardware is scheduled to arrive overnight, and our team will move forward with installation as soon as it becomes available. This replacement is expected to restore full capacity and stability. We will provide a final update once the new hardware is in place and service levels have been fully validated.

  5. monitoring Jun 13, 2025, 05:11 PM UTC

    The replacement hardware has been successfully installed and is now back in production. Inbound call handling on the Orange Platform has returned to normal, and system performance has been fully restored. We will continue to monitor the platform to ensure continued stability, but no further impact is expected at this time.
